Hardness testing on convex and concave surfaces: Unlike the conventional hardness testers which are limited to only flat-surfaced samples, measuring with the Bareiss digitest II allows hardness testing on all surfaces possible by using the automatic surface detection technology. In addition to that, we can customize our indenter length so that it can reach any point on the sample which is required for measuring.
Sample holders and positioning devices: Bareiss offers a wide range of standard sample holders, but we also specialize in customizing holders for your particular products. Please contact the sales team for your individual solution.
Measuring Devices: The easy plug-and-play solution requires no complicated setup. The measuring unit can be securely installed simply by hand fastening a knurl nut and once done, the electronic unit automatically detects the type of the installed measuring method in accordance to that standard.

Measuring devices Shore, A, B,0, D, C, D0, 00, 000, 000S, Asker C, CS:: 1) The electronic unit is switched on and using devices for shore D, C, D0, Asker CS the display shows: Apply additional weights and the loads are applied accordingly. 2) The sample is placed onto the supporting table so that there is proper contact between the surface of the supporting table and the sample. 3) Results are more reliable and precise when the highest point of the sample is below the indenter. 4) The supporting table is moved by hand wheel so that the distance between the indenter and the test specimen is 3mm 5) Press the ‘START’ key and the measuring device is automatically lowered onto the test specimen. 6) Once the measuring time is completed the measuring device moves back to its starting position and the measured value is shown on the display and the data can be transmitted simultaneously. Measuring device Shore, A/B/0:: 1) The loading weight on this measuring device should be in a free-moving position. If it’s fixed in the upper position, push up and rotate against the arrow direction. 2) Care must be taken to check that the indenter is not visible during testing as the loading weight must be movable freely. Measuring device M Shore, A/B/0, M Shore D: 1) The knurled screw is loosened until the loading weight can be moved freely. 2) Care must be taken to check that the indenter is not visible during testing as the loading weight must be movable freely. Measuring device M Shore, A/B/0, M Shore D:: 1) The knurled screw of the pressure plate must be loosened so that the pressure plate can be moved freely. 2) Care must be taken to check that the indenter is not visible during testing as the pressure plate must be movable freely.
- User-Friendly: This automatic shore hardness tester is equipped with an electronic unit that can show user information, time, and method of measurement, and is equipped with various other configurations along with automatic measurement of time and range detection.

The system consists of 4 components, a loading unit, measuring unit, stand, and an electronic display.
The loading unit sits on top of the system and is connected to the display. It applies the required load as specified by the test method.
Measuring units are plug-and-play and available for all the options of Shore and IRHD standards.
The test stand is 22.5" / 570mm tall and the solid construction provides a rigid backbone for the entire system. It is key for generating precise and repeatable measurements.
